There are many types of pre-built compost bins available at area stores and on-line, should you wish to purchase one. However, you can easily construct one on your own (some composters just use a simple hole in the ground!) Here are a few examples of easy to make bins:
Trash Can Bin
To convert a plastic trash can into a composter, cut off the bottom with a saw. Drill about 24 quarter-inch holes in the sides of the can for good aeration. Bury the bottom of the can from several inches to a foot or more below the soil surface and press the loosened soil around the sides to secure it. Partially burying the composter will make it easier for microorganisms to enter the pile.
Wire Bin
Use an 11-foot length of 2-inch x 4-inch x 36-inch welded, medium-gauge fence wire from your local hardware or building supply store. Tie the ends together to form your hoop. A bin this size holds just over one cubic yard of material.
